生物活性:
Efdamrofusp alfa is a bispecific fusion protein. Efdamrofusp alfa is capable of neutralizing both VEGF isoforms and C3b/C4b. Efdamrofusp alfa can be used for the research of neovascular age-related macular degeneration (nAMD) and other complement-related ocular conditions.
体内研究:
Efdamrofusp alfa (13.5 μg; 3 days) inhibits activation ofthe complement system in a mouse model oflaser-induced CNV.Efdamrofusp alfa (1.35 mg; single intravitreal injection) shows favorable safety profiles and exhibited antiangiogenetic efficacy in a nonhuman primate laser-induced CNV model.Animal Model:C57BL/6J mice
Dosage:13.5 μg; 13.0 μg
Administration:3 days; 7days
Result:Significantly reduced C3d deposition.Reduced vascular leakage at 7 days after laser-induced injury.Significantly suppressed CNV formation 7 days after laser-induced injury. Reduced the concentrations of vitreous VEGF-A.
Animal Model:Rhesus monkeys
Dosage:1.35 mg
Administration:Single intravitreal injection
Result:Decreased the CNV leakage at 14 and 28 days and effectively reduced CNV volume 28 days.
